Thanks for the sensor refresh update!

I have Toyota Avensis 2001 and there is active error code P0135. Pyobd is not showing that DTC properly. It sometimes shows that there is no error code. When you click "get DTC" it shows code P0309. When you clikc "get DTC" again, it shows codes P0769 and P01280. ELM327 module is responding 43 01 35 00 00 00 00 to DTC request. Does anyone have any idea, what's causing this behavior?
